Today and tomorrow I'm going to experiment with the following maze:
the most direct path through being highlighted in dark grey (created with Excel!). I intend to overlay this maze onto my environment and place triggers throughout the path. These triggers will play audio cues -- almost audio "clues" -- on the proper path. This maze will be less claustrophoic than it looks as it will cover roughly one square kilometer and have very few literal walls blocking vision.
The key will be audio design and some camera tricks, as well as a fantastic foliage shader that will allow me to move bushes, trees, and grass around like somethin' big is coming at the player.
I'm also going to make the physical paths in game (the ones between areas) look more like the following:
Lots of work to do!
